Hi, Monica! I am the local grant expert, I work for an area bank, not a broker and 95% of what I do is first time buyer purchases. The Federal Home Loan Bank grant, which is only offered by a few local banks in Maryland is getting funds in the beginning of April. If you income qualify you can get up to $7500 (this is in addition to the $8000 tax credit) of forgivable funds to go towards your required down payment and closing costs. In addition, there are a couple programs in the city that currently have funds. You do want to act fast though as the deadline is looming for the first time buyer federal tax credit.
I'm including a link below to some information about the Federal Home Loan Bank grant.
